N The spectral characteristics of localized surface plasmons (LSPs) depend strongly on the geometry of the metal nanostructure sustaining them. [ 1 , 2 ] This fact makes the tuning of their lightharvesting and focusing abilities across the whole visible and infra-red regimes possible. Lately, the tailoring of the spectral width of LSP resonances through… (More)

In this work, we investigated the use of 10-layer InAs quantum dot (QD) as active region of an electroabsorption modulator (EAM). The QD-EAM is a p-i-n ridge waveguide structure with intrinsic layer thickness of 0.4 mum, width of 10 mum, and length of 1.0 mm. Photocurrent measurement reveals a Stark shift of ~5 meV (~7 nm) at reverse bias of 3 V (75 kV/cm)… (More)
